APPARATUS FOROPERATING LEVATOR-DOORS.

To all whom it may concern: 7

Be it known that I, FRED S. PAYNE, a citiin the county of Sufiolkand State of Massachusetts, have invented new and useful Improvements in Apparatus for Operating Elevator-Doors, of whichthe following is a specification, reference being had to the accompanying drawings.

The invention relates to that class of dooroperating devicesinwhich the mechanical. means for opemngand closing the door are controlled by an electric circuit which is 7 made and broken by the movement of the ator.

My objects have been, first, to provide an apparatus which shall allow the door to remain normally closed unless the elevator-car best'ationary at such doorway; second, to provide means controlled by the operator of'the car for opening and closing the door; third, to provide means for causing the door to close upon the movement of the car away from such door. I accomplish these objects by the means hereinafter specified and as illustrated in the accompanying drawings.

Figure 1. represents a partially-open door in an elevator shaft with a portion of the controllingpiechanism. Fig. 2 shows such mechanism in position when the door is closed. Fig. 31sad1agrammat1cv1ew of the,

. electrical connections for the elevator-car and for the doorways on two floors for con trolling the operation of the mechanism shownflin Figs. 1 and. 2.

1 represents an ordinary door in an elevator-shaft.

2 is a rail. 3 and 8 are contact-plates attached to said rail and located at such oints within the elevator-shaft that one 0 such plates will be .in'contact with shoe 4 of car 5 whenever said car is opposite the correspondin'g doorway in said shaft I preferably make rail 2 continuous, so thatiit extends,ap-'

proximately the entire len th of the elevatorshaft, and set lates 3 an 3 into said rail,

so that they Wlll be insulated therefrom and with their outer surfaces flush with the surfaceof said-rail. By so doing shoef4, which is held in sliding contact with tail 2 by any suitable means, is allowed to successively make contact with plates Rand 3 without the jar-which woul moving elevator-car.

Specification-of Letters Patent. ap lication filed July 1,1905. Serial No. 267,878-

elevator-car and the action of the car oper-v I otherwise be incident, to the making of such contact by a rapidly- ?atented Dec. 25, 190.6.

6 represents an ordinary operating-lever Within the elevator-car 7v is a contact-plate onbutin-sulated from .lever 6. 3 8 is a contact-plate so placed as to hem contact with'plate 7 when, and onl when,

lever 6, is in proper position for the e watercar to remain stationary. In the accompanying drawings I have shown plate 8 afiixed .to but insulated from the casing surroundin the lower part of lever 6 and in the center 0 the segment traveled by said lever.

9 is a push-button.v A convenient place to alve 12 is operated by Bar 20 is pivoted at oneend on door 1 and at the other on some stationary support attached to the side of the elevator-shaft. Connecting-rod 21, connects bar 20 with the crosshead of piston 19, which runs in guideslZl",

The particular form of construction of the valve anti-tether mechanical connection between armature 11 and door 1 is not essential to myinverttion, andl make no s ecific claim therefon. Any type of valve w 'ch will al-, low of a reciprocating action being imparted to a iston' and any suitable form of connection etween such piston and the elevator-v door may be adopted, That shown herein is it simple in construction and operation and has the advantage of causing door '1 to remain closed and by using a rule-joint in bar 20 locked until magnet '10 be energized.

22 and 23 are the main su ply and return wires, respectively, connecte( to the positive and negative poles of any suitable electric generator. Wire 22 connects with magnets 10 and 1.0 by branch wires 22?. Wires 24 and 24, respectively, connect contact-plates 3 and 3 with magnets 10 land 10.- Wire 23 connects with late 8, and plate 7 is connected with p'ushutton 9 by wir25 Wire 26 connects said button with shoe 4.

When valve 12 is in normal position, the

operating fluid willenter cylinder 18 through pipes 13 and 15, thereby forcing piston 19 intoiposition shownv in Fig. 2 and door 1 IIO will be closed. Upon the stopping of the elevatorcar before a door, plate 3 and shoe 4 or plate 3 and shoe 4, as the case may be, will be in contact, as will also be plates 7 and 8. If push-button 9 be then pressed, the electric circuit will be completed by means of the Wires and electrical connections hereinbefore described, the roper magnet will become energized, thereby actuating lever 16, which causes valve 12 to operate in reverse action, piston 19 will rise, and the door will be opened. It the electric circuit be broken at push-button 9 or by the starting of the elevator-car and the consequent disengagement of plates 7 and 8 or shoe 4 and plates 3 or 3, lever 16 will be returned to its normal position, as hereinbefore described, and the door will be closed. Should the car not stop at any doorway 'or the operator fail to press button 9, all doors will remain closed.
